or different forms of nectlon with various Be it known that I, HENaY K. SANDELL, a

machines, including citizen of the United States, residing at Chicago', in the county of Cook and State of Illinois, have invented a new and useful Imrovement in Coin-Actuated Devices for lontrolling the Operation of Coin Operated Machines, of which the following is a specitherefore-in its relation to a coin-operated ncatioh. -In coin-operated machines of the class in which the insertion of a coin starts the action of the operating mechanism, the insertion of a second coin, or ofa succession of coins, before the machine has completed its operation as the result of the first insertion," is liable to disorganize the mechanism in one way'oranother. I I The object of my invention is to provide a device for use with machines of the class referred to, whic shall permit a pluralit, of coins to be inserted into a machine wlii c it rated music-sheet for producing the music, like the electrio'slfi-playing yiolin for which Letters Patent No. 807,871 were granted to me Dece'mberig, I905. i A su porting frame Bfor the mechanism of the (iizvice, which may consists of a flat back 7 having an armw8 pro- {Decting horizontally from its upper end and bracket 9, of inver ed- L shape projecting forwardl under the arm 8, from its lower end, and a post 10 projecting from near one edge between the arm and bracket. back 7-is shown'fastened a sheet 11 of insulating material, such as vulcanite fiber, projecting beyond the lateral edges of the back andfitted about the base of the 0st. On thogilgsulated back 7 are fastene the two spool of an electro-magnet 12, the armature 13 of which is supported to extend over the magnet-poles on a flat spring Mfastened by a screw 15 to the foot-portion'of the bracket 9, in which a setscrew 16- works against the under side of'the spring for regulating its tension. In the free end of the armature is pivoted a spring-pressed tongue 17 to project resiliently into a recess 18 provided in'one side and between the ends of a rock-shaft 19 journaled at its extremities in the bifurcated end of the arm 8 (Fig. ,5). tened at one end to the armature extends therefrom lengthwise over the spring 14 and is formed at its free end with a li 7 2-1 projecting into close proximity with the spring to keep the armature in-a straight position by the lip engaging. the spring when the arma ture is attracted and resisting any tendency of the force of the attraction to bend the armature-spring 14.

The screws 22 which fasten the strip got) the armature also fasten thereto a contactspring 23, which is held by the armature, in

cause repeated complete operation of the machine once for each inserted com, and which shall arrest the operation upon comthelast-inserted coin;

A device for the aforesaid purpose em} bodying my invention in a referred con--= striiction, as to matters of etail, is illustrated in the accompanying drawings, in which- Figure 1 represents the device in its nor,- mal condition )y a view in side elevation and coin-chute, shown in vertical sectional elevation; Fig. 2 is a broken section I'taken at the line 2 on Fig. .5 andviewed in the direction of the arrow; Fig. 3, a view like that presented by Fig. l but showing the device with the arts in thefcondition to which they have een brought by the insertion of four coins into the chute before the machine to which the chute result of inserting the first coin ,"Fig. 4, a section like that presented by Fig. 2, but with the parts in. the same condition as that described in connection with Fig.- 3; Fig. 5, a broken bottom plan view of the device with a portion of its ,rimary actuating-- arm bpoken away, and ig. 6, a diagram showing the device as operatively connected-in an electric circuit.

through the lowerslotin thabar into the end 37 vnojecting' laterally from the bracket 9 ram lcl with the rod 35, between which still" and the head of the screw the ratchet-bar is inovably and guidingly confined. The slot is shown to have a transverse bracingcih 38 forming a stop to engage with the rod and limit the upward moveinent of thebar; and the base of the recess 34 rests on the rod. 35 when the bar is in its lowermost position; H I

On the rocloshaft 19, to one side of its eontained recess 18, is secured, to rock with it, an angular bracket consisting of an arni 39, forniingthe inein'ber by which it isso fastened to the rock'shaft, and having aiore ar1nsection 40 extending at a right-angle from its outer end, and a finger 41 extending at a rightangle from the outer end of the section 40 .in'

the direction that thearm 39 extends. When the ratchet-bar 31 is in its lowermost position, the hraoket section 40 extends across it in the .re'cess iie, beinr thrown to that position by the wei 'ht o the lnracket and thereby turning the sihaft 19 part way around sufiiciently to takethereccss 18' out of registration with the armature springftongue 17,

On the free endpf t is c rank-arm is pivoted a mud, that shoivnconsisting of a hook-sha Jed Jody 47, one end of which is pivoted to t. ie crankand by a-screw 36 passing,

arm 46, whence it extends across the rod 35, and a rigid finger 48, forming the pawl Ercaper, extendin r at a right-angle from the o y across the p one of the edge of the ratchet-barprovided with the teeth 32, whereby depressing the trip-fingor 44 turnsth'e sleeve carrying it to enga e thapawMS with the ad jacent ratchet-teeth, to lift theliar 31., as and for the purpose hereinafter "more fully described. On the rod 35 is further mounted to oscillate thereon a sleeve 49 carrying on its inner end a depending pallet consisting of a bod 50 having a detentpawl 51 extending from it across the plane of the ratchet-teeth 32 to engage therewith, and a similar detentpawl 52 extending from it across the lane of the ratchet-teeth 33 to engage with 1; en], thus forming a species of escapenient. The

coiled spring 54 with a rigid pin 55 projecting horizontally from the ad acent side of the armature 13 near its free end; and the detent. 52 is turned upwardly at its free end to form an abutment 53 extending across the plane of the pin 55 against undue turning of the pallet under the stress of the spring 54 and by which to turn the allet for the purpose hereinafter explained w on the arinature is attracted by the magnet. i

With the device in position on a machine with which it is to be used, the""trip-arm 44- ,passes at its free end transversely through and is movable in the longitudinal slot in the coin-chute 56 of such machine, and is thus in the path of the coin-passage through] the chute, "which usually leads to av coin-receptacle (not shown); so that each time acoin ,its weight and momentum depresses the triparm to abouta horizontal position, overco1n ing the resistance of the weight 43, the grav- 'ity of" which returns the arm to itsnormal osition after the inserted coin has rolled oil .it to continue its course through the chute, which is connnonly ,w-idened or deflected toward its lower end to permit the coin to clear thetri 'i-arni after having de ressed it.- Refercnce to the diagram in ig. 6 will facilitate understanding the. description if the operation hereinafter contained:

The part represented at 57 is the contacts rolldr of the aforesaid patent, acrosswhichis fed the perforated music-sheet containing'a perforation at the end of the piece out in the sheet. Thisperforation is represented at 58 by a dotted indication on the roller in a positmn to register its path witha certain contact-finger indicated 817'59. The circuit of a motor; indicated at 60,; for'driw ing the machine, proceeds 'l'rom one side of a generator 61 by a wire w through the motor", whence it connects with the binding-post 3'0; and the generator is connected i'roin its opherefore, won the spring 23 is separated pallet is connected from its detent 51 by a is inserted into the chute it encounters and by of music osite side, h a wire wflwith the'finger, 24:

The wire w is connected by a wire 57, and the contaet finger 59 is connected by a Wire 10" with thewires 27 and 28 which go teorresponding terminals of the magnet 15?, the other terminals of which connect by the wire 26 with the finger 24. The armature-spring 14 tends to ifiaintain the spring 23 in contact with the finger 24' to keep the I out the pla- 'ng of-a piece by the machine; but when this piece is finished, the perforation- 58registers with the contact-finger 59 and connects the wire to through theroller 57 with the finger 59, wire the wire is, thereby energizing the magnet 1.2 to attract the armature and thus separate finger 24 with the result of: opening'the motor-circuit and stop.- ping the motor' The momentum of the mo tor pulling the traveling music-sheet (which is perforated-for playing a pluralityof pieces,

While the ratchet-her remains so raised, it oltstructs the reentry, by

gravity, of'the' bracket-section 40 into the recess 34, thereby maintaining the shaft-jre-..

thus acting in the ordinary manner of the pallet in an escapement.

If, during the play ng of a piece, no 'additional coin is in.-

troduced into the chute to trip the arm 44,.on completion of the iece, when the perforation 58 registers with the contacbfinger 59,

the magnet is energized to attract the arma? ture and thus carry the tohgue 17 through. the recess 18 into'position back of the stop or shaft 19,-fand the movement of the armature engages the pin 55 on it with the abut- .ment 53 tothrow the pallet-pawl 51 ou t'of engagement with the-ratchet-teeth 32' and permit the bar 31 to drop by gravity to its normal position. In attainj 0 that position, the upper end of the rateheii liar withdraws from obstructin the bracketarm- 40'; permitting' the brac et to turn that arm the the shaft'19 to recess 34' thereby also turnin the position represented in g. 2, wherein it remot es the recess 18 outof registration with the tongue 17 and-sto s the' latter to obstruct the return of the aqgatune, under the force of its spring 14, preventing engagement" of the spring 23'WM the finger24, and'threb also, the bracket-finger 4=lis.againv into the path of the weight 43. The arts are then in condition to-,be' again actuated as described as the result'of inserting-another coin to tri the arm 44 and close. the motor circuit an starttheo eration of the machine. In the event inserting oneior a pluralit of coins in succession, into thec'hute While t e'machine is still operating the result of the first coin-insertion, each additional coin so inserted V and actuate the pawl 48 against a diff nt tooth 32, once for each insertion, thereby raising the ratehet-bar.farther and farther and continuing its obstruction 'to the dropping of the bracket-arm 44, so that the shaftrecess 18 remains in registration with, the tongue 17 to permit the armature to engage .the spring 23 with the finger 24, and close the magnebcircuit as the result of each "such insertion Each ensuing'attraetion of the asmatureengages the pin 55 with the pallet to release the ratchet-bar and permititto drop the extent of one tooth, as already de scribed; so. that after the machine hasopen ated as many times as the number of inserted ooins the bar will drop to its lowest position to admit the bracket-bar 40.into its recess 34 and turn the shaft 19 to obstruct the circuit closing action of the armature untilanother [Olir '1'; will trip thearm 14 IRS coin is inserted to produce starting of the motor for operating the machine anew.
